Description

HADOOP-8225 broke MR when security is off. MR was changed to stop re-reading the credentials that UGI had already read, and to stop putting those tokens back into the UGI where they already were. UGI only reads a credentials file when security is enabled, but MR uses tokens (ie. job token) even when security is disabled...
